Quantum dynamics of mesoscopic driven Duffing oscillators
Quantum dynamics of mesoscopic driven Duffing oscillators
We investigate the nonlinear dynamics of a mesoscopic driven Duffing oscillator in a quantum regime. In terms of Wigner function, we identify the nature of state near the bifurcation point, and analyze the transient process which reveals two distinct stages of quenching and escape. The rate process in the escape …
